Great Basin Pipeline Expansion Wins BLM Approval in Nevada
The Bureau of Land Management has approved a right-of-way for Great Basin Gas Transmission's Carson Lateral expansion project in Nevada following federal environmental review.
(P&GJ) — The Bureau of Land Management has approved a right-of-way for Great Basin Gas Transmission Company's Carson Lateral expansion project, allowing the proposed natural gas pipeline expansion to move forward across federal lands in western Nevada.
The approval covers public lands in Washoe and Lyon counties and follows completion of federal environmental review led by the Federal Energy Regulatory Commission.

FERC issued an environmental assessment for the project in December 2025 and concluded that the expansion would not significantly affect the human environment. As a cooperating agency, the BLM participated in the review process and concurred with FERC's findings.
The agency's decision authorizes Great Basin Gas Transmission to expand its Carson Lateral pipeline system across public lands administered by the BLM. The project is currently subject to a 30-day administrative appeal period.
Project Details
According a July 2025 FERC filing, the 2026 Great Basin Expansion is designed to increase firm natural gas transportation capacity by 8,129 dekatherms per day (Dth/d) to serve growing demand from existing customers in northern Nevada and northern California.
The project includes construction of approximately 2.3 miles of new 20-inch-diameter pipeline looping alongside the existing Carson Lateral in Washoe County and replacement of approximately 2.4 miles of existing 10-inch-diameter pipeline with new 20-inch-diameter pipe in Lyon County.
Great Basin filed its application for the expansion in April 2025 under FERC Docket No. CP25-209-000.
Project documents are available through FERC's eLibrary under Docket No. CP25-209-000.
